It is gathered and extended forward.

  Next, the operation of the present embodiment will be described. A part of a bench seat type passenger seat 21 that integrally includes a driver seat and a passenger seat and an auxiliary seat disposed between the driver seat and the passenger seat is configured. The seat seat portion 22 to be able to seat an occupant while covering at least one of the first maintenance space 41A, the second maintenance space 41B, and the storage space 42 (all in this embodiment) from above. Displaceable between the closed position and the open position where at least one of the first maintenance space 41A, the second maintenance space 41B, and the storage space 42 (all in this embodiment) is opened. Is supported by the vehicle body frame F. A seat support portion 40 that supports the seat seat portion 22 in the closed position from below is opposed to the seat support portion 40. The seat seat portion 22 is provided on the vehicle body frame F so that the seat seat portion 22 can be attached and detached, and the rear portion of the seat seat portion 22 and the middle portion in the front-rear direction of the seat support portion 40 are connected via a swing arm 52. Therefore, it is possible to avoid the seat seat portion 22 in the open position from projecting greatly above the seat support portion 40 and to be in front of the seat support portion 40, and to displace the seat seat portion 22 to the open position. By doing so, the upper openings of the first maintenance space 41A, the second maintenance space 41B, and the storage space 42 can be greatly opened.

  A seating sensor 51 for detecting the seating state of the occupant on the seat seat 22 is provided on the seat seat 22, and a sensor cord 55 connected to the seating sensor 51 is wired along the swing arm 52. Therefore, it is not necessary to remove the sensor cord 55 when displacing the seat portion 22 to the open position, and the work of removing the sensor cord 55 can be omitted to improve workability.

  Further, since the sensor cord 55 is held by the swing arm 52 via the clip 56, the sensor cord 55 is held by the swing arm 52 when the seat seat portion 22 is displaced to the open position. , Workability can be further increased.

  Further, the front edge portion 22a of the seat seat portion 22 in the open position is positioned between the seat support portion 40 and the instrument panel 57 disposed in front of the seat support portion 40. Since the connecting position of the swing arm 52 to the seat seat portion 22 and the seat support portion 40 is set, the seat seat portion 22 in the open position is arranged using the wide floor portion in front of the riding seat 21. In this way, a large amount of displacement from the closed position to the open position of the seat portion 22 can be secured.

  Moreover, the seat support portion 40 is provided on the vehicle body frame F so as to rise upward from the front floor 19, and the front edge portion 22 a of the seat seat portion 22 in the open position is from the upper surface of the front floor 19. Since the seat seat portion 22 in the open position is supported by the swing arm 52 and the front surface 40a of the seat support portion 40 so as to be disposed at a position spaced apart upward, when in the open position The front edge portion of the seat seat portion 22 does not contact the upper surface of the front floor 19, and the front edge portion 22 a of the seat seat portion 22 can be prevented from becoming dirty due to contact with the front floor 19.

  Further, the swing arm 52 made of metal is formed to extend linearly so as to be able to rotate with the connecting portion 53 of the one end portion of the swing arm 52 to the sheet support portion 40 as a fulcrum. Therefore, when returning the seat portion 22 from the open position to the closed position, the swing seat 52 can turn the seat seat portion 22 in a fan shape to return to the closed position, thereby further improving workability.

  In addition, a long hole 58 that extends long in the front-rear direction in the state where the seat seat 22 is in the closed position is provided at one end of the swing arm 52 at the intermediate part in the front-rear direction of the seat support part 40. And a fitting hole 59 provided at the rear portion of the seat seat portion 22 and provided at the rear portion of the seat support portion 40 and opened forward. Since the mating projection 60 is provided in a projecting manner, the seat seat 22 can be slid in the front-rear direction by the long hole 58 when the seat seat 22 is in the vicinity of the closed position. The fitting projection 60 can be fitted to and released from the fitting hole 59 in the closed position, and the support structure of the seat seat 22 to the seat support 40 in the closed position can be simplified.

Therefore, the space to be secured around the bolt 79 can be reduced in order to arrange the rotary switch 84 for detecting the relative rotation position change of the seat back portions 68 and 69 with respect to the seat seat portion 67.

  The rotary switch 84 is interposed between the base member 87, the inner rotary 88 accommodated in the base member 87 so as to rotate together with the mounting stay 78, and the base member 87 and the inner rotary 88. Since the base member 87 is supported on the support stay 73 side with the connector portion 87a provided on the base member 87 facing downward, the inside of the rotary switch 84 is provided. It is possible to suppress water intrusion to the water as much as possible and improve waterproofness.

  Further, since the seat frame 70 is mounted on the floor portion 20a of the loading platform 20 provided at the rear portion of the vehicle body frame F included in the rough road traveling vehicle, the upper portion of the loading platform 20 is opened. Although a large amount of water may accumulate on the loading platform 20, the structure of the rotary switch 84 with improved waterproofness can prevent water from entering the rotary switch 84.

  Further, since the rotary switch 84 is disposed between the support plate portion 73a of the support stay 73 and the mounting stay 78 disposed on the inner side in the vehicle width direction of the support plate portion 73a, a special protective structure is provided. It is possible to simplify the protective structure by protecting the rotary switch 84 without the need to provide the switch.

  Further, the rotary switch 84 is arranged on one side of the seat seat portion 67 in the vehicle width direction, and the end tongue plate 102 provided on the seat belt 96 for restraining the occupant sitting on the seat seat portion 67 can be engaged and disengaged.
